Changes in competitive environment (6) - CORRECT ANSWER✔✔-- Rapidly
| | | | | | | | |
evolving technologies |
- Complex products
| |
- Consumer demands
| |
- Time to market (TTM - Quicker product delivery to marketplace critical for
| | | | | | | | | | | | |
profits but must not compromise on quality to meet demands)
| | | | | | | | |
- Cost competitiveness
| |
- Global trends (Less government regulations, Globalization of companies eg
| | | | | | | | | |
Mergers & acquisitions may mean development sites geographically separated,
| | | | | | | | |
Shared R&D resources may mean dispersed design centers, Outsourcing, Global
| | | | | | | | | |
collaboration may mean project distribution) | | | |
Strategic Plan Steps (6) - CORRECT ANSWER✔✔-1. Identify company mission
| | | | | | | | |
2. Identify strengths, weaknesses & long-range business objectives
| | | | | | |
3. Select market segment to pursue
| | | | |
4. Formalize process for product selection for development
| | | | | | |
5. Select product and identify strategic and tactical issues that must be resolved
| | | | | | | | | | | |
6. Project financial returns from selected markets and products
| | | | | | | |
,Cons of traditional design process (5) and result - CORRECT ANSWER✔✔-- Limited
| | | | | | | | | | |
communication btwn deps
| | |
- Minimal understanding of customer reqs
| | | | |
- Loosely defined guidelines/process
| | |
- Missing 'Lessons Learnt' database integration
| | | | |
- Customer Support Business and other staff only see design at design review
| | | | | | | | | | | | |
stage - almost complete → Any revisions resulting from design reviews costly,
| | | | | | | | | | | |
difficult to implement, time consuming ∴ partially or not implemented
| | | | | | | | |
⇒ RESULT = DELAYED MARKET ENTRY
| | | | |
Concurrent Engineering Approach - CORRECT ANSWER✔✔-Design approach that
| | | | | | | |
merges product design & manufacturing - based on the parallelization of tasks
| | | | | | | | | | | |
(i.e. concurrently) in order to reduce time to market
| | | | | | | |
Attempt to balance 3 Key Factors: Good, Cheap, Quick
| | | | | | | |
3 Characteristics of Concurrent Engineering - CORRECT ANSWER✔✔-1.
| | | | | | | |
Decentralized Design |
- Concurrent work creates cross-functional teams with tight link btwn all
| | | | | | | | | | |
participants in dev process | | |
- Manufacturing and assembly considered in early stages of product design
| | | | | | | | | |
2. Compliance with Customer and Internal Requirements
| | | | | |
,- Customers = all stakeholders (e.g. for aircraft manufacturers - airlines, airports,
| | | | | | | | | | | |
regulators, maintenance crews, pilot, passenger, investors, team members)
| | | | | | |
- Provides methods for rating importance of specific product features using
| | | | | | | | | | |
customer input; then compared to competitive products
| | | | | |
3. Design for Manufacturing, Assembly, and Service
| | | | | |
- Prioritizes ease and speed with which product can be assembled, tested, and
| | | | | | | | | | | | |
repaired
6 Benefits of Concurrent Engineering - CORRECT ANSWER✔✔-1. Reduced
| | | | | | | | |
development time due to less rework from intermittent multidisciplinary reviews
| | | | | | | | |
- Reps from diff groups can better consider trade-offs & design choices as each
| | | | | | | | | | | | | |
decision is made | |
- Fewer engineering/late changes
| | |
2. Quicker Time-To-Market ⇒ higher profits
| | | | |
3. More accurate cost estimates
| | | |
4. Higher quality product in terms of manufacturability, assembly, and
| | | | | | | | | |
serviceability
5. More aligned product with customer + internal requirements
| | | | | | | |
6. Higher productivity
| |
, - Emphasis on problem solving (not placing blame on other group for mistakes)
| | | | | | | | | | | |
When not to choose Concurrent Engineering and why? - CORRECT ANSWER✔✔--
| | | | | | | | | | |
When product is simple or incremental change is marginal
| | | | | | | |
- CE difficult and requires admin + communication overhead + effort to change
| | | | | | | | | | | | |
company culture |
How to Succeed with Concurrent Engineering (7) - CORRECT ANSWER✔✔-1.
| | | | | | | | | |
Create cross-functional teams + design concurrently w product
| | | | | | | |
- Communication between teams is crucial
| | | | |
2. Improve communication system w customer
| | | | | |
- Using shared platform, reviews, etc
| | | | |
3. Involve suppliers + subcontractors early
| | | | | |
- Don't want to design a product that's impossible to produce
| | | | | | | | | |
4. Simulate product & process performance
| | | | | |
- Integrate CAD tools with product model
| | | | | |
5. Integrate technical reviews
| | | |
- Eliminate complexity for complexity's sake, keep it simple and low cost
| | | | | | | | | | |
